Congratulations Jappy.

To go slow with small dosages is the best way to go. I started on half a dose of Avonex, but I had wished I had started on a lower dose. I got symptoms even on the half a dose.
Some people react, others are lucky and don't. I hope you don't have any problems and it works well for you.
Good luck for Friday. 3 weeks is the way to go.
